Yes it is a job you and a beer drinking buddy can do in a day in your garage. You must take the head off and examine the gasket real good for the burnt place where it is leaking. One good first thing to do is pull the sparkys and see if one or more has rust on it.
Your problem from the first was prolly a small coolant leak from the radiator or a corresponding hose. You should find that leak before you consider the job is done! Without finding the original leak it will happen again.
Don't forget to install a new 195* thermostat when you put it back together.
Do not use any sealant on the head gasket.. Clean all surfaces real good before putting it back together.
If a gasket leak is not found then you might have to take the head to a shop for futher examination.. you MUST find the internal leak before reinstalling. You WILL need a torque wrench and know the torque sequence.
